They even admit it (from that link)
In addition, the Mass is another sign of the Christian fulfillment of the Law (Matthew 5:17-18), because it is in harmony with ancient Jewish traditions. We use stone altars, as the Jews did. Priests also ritually wash their hands before celebrating the Sacrifice, in accordance with commands from the Old Testament (Exodus 30:17-21, Psalm 26:6). Even the use of holy water at parish entrances has its roots in Judaism. Before entering the Temple, Jews were required to undergo immersion in a mikveh (ritual bath).
And then, following some of the links from there, it's interesting to see all the divisions in their religion just in the liturgy alone...Here's one example where they attack the Tridentine form of the mass...
Unfortunately, within this liturgical framework, there is a minority that puts its personal preferences above the judgment of the Church. There are some that insist on identifying only with the Tridentine form (which, by the way, was not even promulgated until 1570, despite its proponents’ focus on antiquity) and push willful neglect of the perfectly-valid Novus Ordo, and there are some that advocate the reverse. Both sides are wrong – both forms are right. These factions do nothing but needlessly scare off potential converts that seek a unified message.
Following the old Jewish Laws will send everyone who does so to Hell...
“Following the old Jewish Laws will send everyone who does so to Hell”
My point exactly...I said “Jesus came to redeem us from the curse of the law....ceremonial law, that is the old Jewish Laws.
